Quite possibly. But, only Christ knows for certain the folks given to Him by the Father.

This gives rise to two additional questions:

1) does that mean you don't subscribe to the doctrine of eternal security? I repented of my sins and made a decision to follow Christ in 1997 when invited to do so by a pastor at an evangelistic event in Washington D.C., and have sincerely followed Christ since then. If I was saved then, and if it's impossible to lose that salvation, I don't see why I should be worried merely by having changed ecclesiastical addresses.

2) How can one be saved and remain in a church from which one should, in your words, "escape?"

I will give you credit for at least one thing: the overwhelming majority of our evangelical friends abandoned us as apostates when we told them of our conversion to Catholicism. At least you're admitting the possibility that we're still Christian!
